AFC Champions League Two

The AFC Champions League Two (abbreviated as the ACL Two or ACL2) is an annual continental club football competition organised by the Asian Football Confederation. It is the second-tier competition of Asian club football, ranked below the AFC Champions League Elite and above the AFC Challenge League.

The competition was founded in 2004 as the AFC Cup, it was played primarily among clubs from nations that did not receive direct qualifying slots to the top-tier AFC Champions League. The competition rebranded to its current name in 2024. In a bid to increase competitivenes, its format was also changed to include clubs from higher ranked AFC member associations. The prize money was also increased.

Clubs qualify for the competition based on their performance in national leagues and cup competitions. Participation in the competition is open to clubs from the top 12 nations in the East and the West region based on the AFC club competitions ranking. The participant from each nation ranked 1–6 in each region is the highest-placed club in that nation that did not qualify for the AFC Champions League Elite. The nations ranked 7–12 in each region enter their top club(s) directly to the AFC Champions League Two.

The winner of the AFC Champions League Two will be allocated an indirect preliminary stage slot for the next AFC Champions League Elite season, if they have not already qualified through domestic competition. The current champions of the competition is Central Coast Mariners, who defeated Al-Ahed in the 2024 final. Al-Kuwait and Al-Quwa Al-Jawiya are the most successful clubs in the competition's history, having won three titles each. Clubs from Kuwait have won four titles, making them the most successful nation in the competition.
